If you have a xforce exhaust, isn't the rear muffler to restricted? so might be better getting rid of it all together.

has any one got the twin 3 inch manta system with a 4inch dump??

im getting it put on now and just seeing how it sounds is it worth getting the centre mufflers out

Dre's got one but his cars getting tuned atm, I think it's suppose to be done mid week.

I think it would be way too loud with the centers out.

interesting read impellor! wouldnt mind hearing it to see what difference it is to stock. how much would your mate charge for doing something like that?

The cost was $165, sounds much better. I have heard the centre muffler removal which sounds a bit like a tractor at idle, in my opinion this sounds much better, could have something to do with the 76mm pipes. Further, straight away everyone notices the twin 3 inch tips. They fill the cutout nicely, doesn't look to big, just right I'd say. Cheers

Do you get any crackle Impellor? and how loud would it be compared to a cat back system?

I think rear removed (centre in) is better at idle and low revs, centre out (rear in) is a bit tinny on start up and low rvs but better above 3,000rpm to my ears. Just my 2 cents and yes, I've heard both as I did both to my car. But every T is different with mods, models, how the pipes are fitted etc etc which would change the result

Dillz is right, twin 3 inch without centre (and high rwkw) would be very loud Blckphn. Which state you are in could mean some unwanted attention for noise limits etc? (in Tas you could have a NASCAR and no one seems to care, but then in Vic/NSW is much more policed from what I've heard....? )

mine doesnt sound tinny at all, I recon it sounds more like a wannabe V8. (in a good way). has a pretty deep idle which sounds dam .

dunno what it sounds like when driving though. mines its loudest from 1500rpm to 2500rpm give or take. anything around this its not so bad. I really need someone to drive it so I can follow and listen. keep yas posted on this.

I had a cat back on my old VT V6, I would say its much the same. VT had centre muffler and a rear resinator. 2 1/2 inch from memory.

FordFreak, mine had a deep idle when warm also, but was very tinny loud on cold (ie; 0 degrees) starts ups - the FGs aren't as noticable as they are a fair bit quieter than BA/BF with centre removed on stock exhaust.

Yes, mine was loudest (still is, but much louder again) at around 2,500rpm

Anyone rolling around with both removed??
